Dear Maintainer,

I noticed this error message after upgrading to bookworm a while
ago. It doesn't have to have any ill-effect.  The full message
from boot.log.1 is:

Begin: Running /scripts/local-bottom ... /scripts/local-bottom/mdadm: 2: /scripts/local-bottom/mdadm: rm: not found
done.

and the file in question appears to be installed by mdadm to
/usr/share/initramfs-tools/scripts/local-bottom/mdadm:

#!/bin/sh
rm -f /run/count.mdadm.initrd
exit 0

On my system /bin/sh is symlinked to /bin/dash so dash
cannot find the `rm` command.  /bin is symblinked to usr/bin/
which has the `rm` binary.

This appears to be a regression of #875918 that was fixed in 4.1-9
while I am running 4.2-5.

Auto-generated on Tue, 24 Sep 2024 03:42:05 -0400 by mdadm bugscript

Control: severity -1 normal
Control: found -1 mdadm/4.4-5

This reproduces on fresh installs of trixie, the log message there
reads:

/scripts/local-bottom/mdadm: 2: /scripts/local-bottom/mdadm: rm: not found

It appears nothing ensures (/usr)/bin/rm is actually copied into the
initramfs.

Could this please be fixed in time for the release?

Thanks,
Chris

indeed, I haven't seen it :(

I'll have a look at it on Monday after the holidays and aim for an
unblock :)

Hi,

hmm.. I had a look at this several times, however, I coudn't find out
why 'rm' isn't working at that stage/place in initramfs, where it
clearly works before or afterwards for other packages.

I'll give it another go tomorrow.

Regards,
Daniel

I just had another look at this bug. It happens only on machines
which do not have "busybox" installed.

IIRC initramfs-tools can use various tools either from busybox or
from coreutils and klibc-utils. I *guess* if busybox is installed,
busybox and all links to it get installed unconditionally. This does
not happen if busybox is not installed.

Probably the easy way out is to unconditionally have the mdadm hook
script install /bin/rm into the initramfs.

Chris

[..]

Daniel, did you find some time for this?
